fi'aaen'ckt'. Mn/acA er Patented Oct. 1, 1929 UNI TED STATES PATENT OFFICE FREDERICK E. THEILACKER, OF MILWAUKEE, WISCONSIN, A SSIGNOR TO NORMAN I. HARSHBERGER, OF CHICAGO, ILLINOIS SHIN GLE Application filed August 30, 1926. Serial No. 132,345.

This invention relates to flexible strip shingles and more particularly to composition shingles. However, it is applicable to any type of shingle that is more or less flexible, such as sheet metal shingles. The invention has for one of its objects producing a strip shingle the lap portions of which may be locked down in an improved manner. A further object of the invention is to provide shinglesof this nature that can be cut from sheets of shingle material without waste. Another object is to form the shingle so that the above mentioned objects are met, and at the same time the assembled shingles present a very pleasing appearance.

Of the accompanying drawings Fig. 1 is a plan view of a number of the shingles assembled as they are ordinarily laid on a roof; Fig. 2 is plan view of a single shingle; and Figure 3 is a plan view of a somewhat modified type of shingle; and Fig. 4 is an en- Ilfiarged sectional view along the lines 44 of Each of the shingles 5 has lap portions 6 projecting from one edge of the shingle. In practice there may be as many of these lap portions as may be desired. I prefer to have only two. Near the outer edge of each of these lap portions is a slit or slot 7 which is adapted to assist in looking down the lap portion when it is laid on a roof. Slits 8 are cut in the main body of the shingles between two lap portions, forming lugs or looks 9 which are adapted to slip into the slots 7 of the overlying shinglesand thus to lock down the lap portions 6 of the overlying shingle. Slits.

10 are also out in the body of theshingle, forming lugs 11 therein which are also adapted to slip into the slits 7 of the lap of the overlying shingles.

By a, consideration of Fig. 2 it=will be seen that each of the laps 6 islocked down by a lug 9 of an underlying shingle, or by two lugs 11 of adjacent underlying shingles. By having strip shingles with two or more lap portions 6, instead of individual shingles with a s' le lap'portion, not only is the cut- .ting and aying of the shingles carried out more expeditiouslyand cheaper but one of the laps in each s ingle, as stated, is locked proving the appearance and also strengthen- 2 ing the locking; because the single lug 9 is supported by the body portion of the shingle on the two sides, while the lugs 11 are not only weaker, being one-half the width of the tongues 9 if symmetrical, but they are supported on only one side by the body portion. Furthermore, with my shingles fewer nails are required and the shingles are more firmly held in position. They are not only locked together at two points but also two nails will prevent any rotary movement of the entire shingle although the shingles themselves are normally twice the size of individual shingles.- Nails 12 are ample ordinarily for'supporting the shingles, but if desired nails 13 may be also used. By positioning the nails as indicated the lower portions of the bodies of the shingles are firmly fastened, and, particularly, the portions .which support the lugs are held firmly down against the roof.

The particular angle formed between the body portion and the lap portion of the shingle obviously is not material so far as my invention. is concerned. In Fig. 3 this angle is materially smaller than in Fig. 2. As a consequence-the design of the roof is changed. While the principal figure of the design is a hexagon yet the hexagon is not equilateral as is shown in Fig. 2.

In the modified shingle 14 of the Figs. 3 and/1, the slits 15 are made at oblique angles with the edge of the shingle, instead of at a right angle as is the case with the slits 8 and 10. By making the angles 16 less than right angles, as indicated, the lugs 17 converge towards the outer ends and thus, for a given loo,

tion than is the case with the ends 21. This is done in order to provide sufficient length on one of these ends to make a slit 22 and thus form a lug 23 which is spaced from the lap 20 the same distance as the lug 17. By this arrangement a lug is not required at the other end of the shingle as the lug takes the place of the lug 11 in one shingle and also the lug 11 in the adjacent end of the adjacent shingle, the tongue 23 slipping into a slot 18 and performing the same function as the lug 17. Also, to improve the appearance of the shingles the slits 15 and 22 are made parallel with the respective adjacent edges of the laps which are locked down by the tongues, thus improving the appearance of the roof as the design of the lug is symmetrical with the design of the laps themselves.

It will be obvious that the modified shingles 14 may be cut from strips of shingle material in a manner similar to the shingles 5, but with the ends 19 and 21 offset as explained; and in order that the lugs 23 may be similar in shape to the tongues 17 a portion 24 is left on the end 21 and taken off from the end 19, of the adjacent shingle. However, in order to form the shingles 14 more symmetrical, the

. shingle 25 may be used. This shingle is similar to shingles 14, except that a portion 26 projects outwardly from one end, which is cut from the other end of an adjacent shingle, so

that the edges 27 and 28 are symmetrical with reference to the shanks or laps 29. This arrangement provides for equal laps at the ends of the shingles, instead of a long lap at one end and a short lap at the other end of the same shingle as is the case with shingles 14. This makes a better protection for the roof.

For instance, rain could drive under the edge 32 to the edge 33 easier than if the edge 33 were opposite the center of the lug 17 of the overlying shingle. I

I have herein referred to the laps of, the shingles, as the shank portions, 6 or 20, which project from the body portions of the shingles. But it will be seen that the exposed poltion of each shingle, which is frequently called the lap, includes a material part of the body portion as well as the shanks.

I have found it desirable to make a crimp 52, Fig. 3, in the base of the lugs of these shingles so as to raise the lugs above the bodies of the "shin les. This facilitates entering the portion, each of the laps having a slit adjacent its outer end, and a lug fixed to the body portion between two laps, said lug being adapted to pass into a slit in a lap of an overlying shingle, said shingle having a slit extending into said body portion between one end and the adjacent lap, the latter slit in each shingle being spaced from its adjacent lap the same distance as the other end of the body is from its adjacent lap.

3. A shingle having a body portion and two laps projecting from one side of the body, each of the laps having aninternal slit adjacent its outer end, and a lug fixed to the body portion between the two laps, said shingle having a second slit extending into the body portion between one lap and the adjacent cor: ner of the body of the shingle, and having the body end adjacent said second slit positioned materially further from the adjacent lap than the distance the opposite body end is from its adjacent lap.

In testimony whereof, I hereunto set my" lugs in t e slits, and causes the lugs to lay flat down on the surface of the shingles below the slits.

I claim as my invention:

1. A shingle having a body portion, and a' plurality of laps projecting from one side of the body portion, each of the laps havin a slit adjacent the outer end of the lap, an a lug fixed to the body portion between one end and the adjacent iap, said lug being adapted to pass into a slit in a lap of an overlying shingle, the inner edge of said lug being
